Is the judge function useful for a stat I want to max out?
Like, for example, I have a modest Pokemon and use the power lens on it to max out the sp. atk. Does it matter if the judge says it's no good or just decent at getting sp. atk? Does it make a difference if it is best or fantastic?

Or if I'm going an all-out sp. atk anyway should my judge go on other things like HP, speed, etc and ignore sp. atk?
